“Moreover he said unto me, Son of man, eat that thou findest; eat this roll, and go speak unto the house of Israel. 2So I opened my mouth, and he caused me to eat that roll. 3And he said unto me, Son of man, cause thy belly to eat, and fill thy bowels with this roll that I give thee. Then did I eat it; and it was in my mouth as honey for sweetness.” Eze. 3:1-3

To those that are willing to eat (spiritually) the word of God, they will always find it sweet. It is those that resist it that find it bitter.
